Fix up NVRAM settings for boot-device and boot-args.

Browse Source 
This patch originally started as a fix for PPC, in that the NVRAM initialiser wasn't been run on startup (this is why printenv 
on PPC always showed much much less than on SPARC). However, it also showed up some inconsistent logic for boot device 
selection, which must also happen *before* boot is called in order for load to work correctly. With this patch applied, bootpath 
and bootargs are set from boot-device and boot-args respectively on startup for SPARC32, SPARC64 and PPC.

Note: there is a small chance SPARC32 may break on some images - please let me know if it does.
